This is the 12" version of Kicker's KSR Substations. I have had this in my 1992 Lexus ES300 and it is ROCK-SOLID. It is one of the quickest ways of adding BASS to your existing factory setup. I believe the specs on can be found at www.kicker.com, if I recall the wattage is 300watts and it has its own built-in amp. I have used this piece for 1 year and its in mint condition. Oh by the way, somewhere close to ATLANTA is preferred, this box is a big piece. If you're interested please email me at [email protected]. Serious buyers only, please.
